Participants with physical limitation and high degree of pain had poor mental and physical health-related quality of life. In addition, the more support and exercise that the participants had, the more likely they were to report better health-related quality of life.
Osteoporosis is a public health threat worldwide. The aim of this study is to examine the effects of individual demographics, disease characteristics, and social support on health-related quality of life (HrQoL) of adults with osteoporosis. Most psychosocial studies focused on the relationships but not the specific construct of social support on HrQoL.
In a correlational design, face-to-face, structured interviews were employed to collect information. Study questionnaires included a demographic sheet, the modified Social Support Inventory, and the Short-Form 36 scales on a convenience sample of 161 individuals recruited from four outpatient centers. Using the structural equation modeling approach, all relationships among factors, mediators, and HrQoL were analyzed.
The mean duration of osteoporosis was longer than 5 years. Participants who exercised more than three times per week had greater HrQoL than individuals who exercised less frequently. Participants with physical limitation and high degree of pain had poor mental and physical HrQoL. The more support that the participants perceived, the more likely they were to report better HrQoL. The best fitted structural equation modeling (SEM) model included individual demographics and physical function, and social support as significant predictors on HrQoL, with informational support and physical function acting as mediators in those relationships. Moreover, this structural model explained 35, 42, and 40 % of the variance on activity of daily living (ADL), physical, and mental health-related quality of life.
The more informational support that individuals have, the more likely they were to report better HrQoL. Individuals with osteoporosis who have lower pain and more exercise are considered having better HrQoL. Further longitudinal research will help clarify the direction of these relationships.
身体有局限且疼痛程度高的参与者在心理和与身体健康相关的生活质量方面较差。此外，参与者获得的支持和锻炼越多，他们报告的与健康相关的生活质量越好的可能性就越大。
骨质疏松症是全球范围内对公众健康的威胁。本研究的目的是检验个体人口统计学特征、疾病特征和社会支持对患有骨质疏松症的成年人与健康相关的生活质量（健康相关生活质量）的影响。大多数心理社会研究关注的是关系，而非社会支持对健康相关生活质量的具体构成要素。
在一项相关性设计中，采用面对面的结构化访谈来收集信息。研究问卷包括一份人口统计信息表、修订后的社会支持量表以及36项简式量表，对从四个门诊中心招募的161名个体的便利样本进行调查。使用结构方程模型方法，分析了各因素、中介变量和健康相关生活质量之间的所有关系。
骨质疏松症的平均病程超过5年。每周锻炼超过三次的参与者比锻炼频率较低的个体具有更高的健康相关生活质量。身体有局限且疼痛程度高的参与者在心理和身体方面的健康相关生活质量较差。参与者感知到的支持越多，他们报告更好的健康相关生活质量的可能性就越大。拟合度最佳的结构方程模型（SEM）包括个体人口统计学特征和身体功能，以及社会支持作为健康相关生活质量的重要预测因素，其中信息支持和身体功能在这些关系中起中介作用。此外，该结构模型解释了日常生活活动（ADL）、身体和与心理健康相关的生活质量方面35%、42%和40%的方差。
个体获得的信息支持越多，他们报告更好的健康相关生活质量的可能性就越大。疼痛较轻且锻炼较多的骨质疏松症患者被认为具有更好的健康相关生活质量。进一步的纵向研究将有助于阐明这些关系的方向。
